What is K9 Advantix II?

K9 Advantix II is a monthly preventative for dogs that offers comprehensive protection against ticks, fleas, mosquitoes, biting flies, and chewing lice. K9 Advantix II is a top veterinarian-recommended brand because it repels and kills all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks). K9 Advantix II kills 98-100 percent of fleas within 12 hours and continues working for one month to prevent infestations. Fleas and ticks are killed on contact with a treated dog, which means that fleas don't have to bite and ticks don't have to attach to die. This helps prevent transmission of flea-borne and tick-borne diseases such as tapeworms, Lyme disease, tick paralysis, ehrlichia, and Rocky Mountain spotted fever. Killing fleas before they bite may also help prevent skin allergies caused by flea saliva. As well, K9 Advantix II repels mosquitoes before they bite, which may help prevent transmission of heartworms. K9 Advantix II protects your pet before parasites have a chance to bite, not after.

For:

Dogs and Puppies (7+ weeks of age, weighing 4+ lbs)

Benefits:

  • Repels and kills disease-carrying fleas, ticks, and mosquitoes before they bite
  • Kills all life stages of fleas (eggs, pupae, larvae, and adult fleas) and ticks (Deer ticks, American dog ticks, Brown dog ticks, and Lone Star ticks)
  • Kills 98-100 percent of adult fleas within 12 hours
  • Ends flea life cycle by preventing flea offspring (eggs, pupae, and larvae) from maturing into adult fleas
  • Repels biting flies and kills chewing lice
  • Provides one month of protection against ticks, fleas, mosquitoes, biting flies
  • Waterproof - remains effective following a shampoo treatment, swimming or after exposure to rain or sunlight

How does K9 Advantix II work?

K9 Advantix II combines imidacloprid and permethrin to repel and kill fleas, ticks, and mosquitoes. Both ingredients work on contact, attacking parasite nerve cells at different sites. Together these ingredients overwhelm the nervous system killing the parasite. Pyriproxyfen is an insect growth regulator. K9 Advantix II topical solution also repels biting flies and kills lice.

Cautions:

DO NOT USE ON CATS. Cats cannot metabolize the ingredients used in this product. Cats must be separated from dogs during treatment. Do not allow your cat to come in contact with a treated dog for 24 hours. Some small and medium dogs may have an adverse skin reaction.

Brand Name:

K9 Advantix II (Bayer)

What is the most important thing I should know about K9 Advantix II?

The active ingredients in K9 Advantix II are Imidacloprid (8.8%), Permethrin (44.0%), and Pyriproxyfen (0.44%). K9 Advantix II is for use on dogs and puppies weighing 4 lbs or more and 7 weeks of age or older. It is used for the topical prevention and treatment of ticks, fleas, mosquitoes, biting flies, and chewing lice on dogs. K9 Advantix II repels and kills ticks including deer ticks (the major carrier of Lyme disease), American dog ticks, Brown dog ticks and lone star ticks. Additionally, K9 Advantix II repels and kills all life stages of fleas, repels and kills mosquitoes, kills chewing lice, and repels biting flies. K9 Advantix II is a non-prescription (OTC) product available as 0.014 fl oz (0.4 ml) applicators for dogs 4-10 lbs (Green), 0.034 fl oz (1.0 ml) applicators for dogs 11-20 lbs (Teal), 0.084 fl oz (2.5 ml) applicators for dogs 21-55 lbs (Red), and 0.135 fl oz (4.0 ml) applicators for dogs over 55 lbs (Blue).

What should I discuss with my veterinarian before giving K9 Advantix II to my pet?

Consult a veterinarian before using on medicated animals and debilitated, aged, pregnant or nursing animals.

How should K9 Advantix II be applied?

For use only on dogs. Do not use on cats or on other animals. Have your dog stand for easy application. Part the hair on your dog's back between the shoulder blades, until the skin is visible. For dogs up to 20 lbs, apply the entire contents of the applicator tube to 2 or 3 spots on the top of the back from the shoulder to the base of the tail. For dogs 21 lbs and over, apply the entire contents of the applicator tube to 4 or 6 spots on the top of the back from the shoulder to the base of the tail. If your household has cats or other pets, separate them from the treated dog for 24 hours.

What are the potential side effects of K9 Advantix II?

Monitor your dog after application. Side effects may include signs of skin irritation such as redness, scratching, or other signs of discomfort. Gastrointestinal signs such as vomiting or diarrhea have also been reported. If these or other side effects (such as lethargy or agitation) occur, consult your veterinarian or call 1-800-422-9874. Individual sensitivities, while rare, may occur after using any pesticide product for pets. A small percentage of dogs have had adverse reactions to K9 Advantix II. A sensation of burning, tingling, itching, redness or numbness of the skin may occur after topical application. This sensation usually begins 1-2 hours after application. In addition, reactions have occurred in cats that have been exposed to a medicated dog. That is why it is important to separate your cat from a medicated dog for 24 hours. Bayer, the manufacturer of K9 Advantix II, indicates that some of these symptoms will dissipate within 48 hours; however, if your pet is experiencing adverse reactions, please complete the following steps:

  • Stop applying the medication
  • Wash your dog with a detergent based soap (Dawn or Palmolive dish detergents work best). Do not scrub the affected area, as this may cause more skin irritation. Please note: This process is applicable for both dogs and cats.
  • Call your veterinarian
  • Call Bayer Emergency Support Line at 1-800-422-9874. Let Bayer know your dog is having an adverse reaction to K9 Advantix by calling 1-800-422-9874. This line is staffed 24 hours a day, 7 days a week.

What happens if I miss giving a dose of K9 Advantix II?

If you miss a dose, apply the next dose as soon as possible and resume a monthly schedule.

What happens if I overdose my pet on K9 Advantix II?

Contact your veterinarian or veterinary emergency room.

My dog is 9 lb...I used the right stuff for my size dog....I still see flees on my dog

Asked by: Lauri
In order for K9 Advantix to kill fleas, they need to bite your pet to ingest the medication. Therefore, any new fleas that attach to your dog may bite him before they ingest the medication and die. This may be causing the itchiness and scratching your dog is experiencing. It is also important to treat the surrounding environment for fleas, to prevent new fleas from attaching to your dog. However if you purchased the medication from us we do offer a 100% guarantee on all our products.

MY dog gets a seizure when I put any kind of heart worm meds on her. This makes her unprotected from mosquitoes. Is there any reports of seizures with this medicine? Are there any of the same ingredients in any heart worm med. that is in this.? 

Asked by: nancy
The ingredients in K9 Advantix are different from those in heartworm medications. However, since your dog has a history of seizures, I recommend consulting with your veterinarian to determine which flea and tick preventative would be the safest for your dog. Your veterinarian knows your dogs medical history and would be able to make the best treatment decisions regarding your pet.

K9 Advantix should be applied on your pets skin, and not their fur. If you apply the contents on the fur, it may not get absorbed into the skin. You may need to redose your pet if it looks like the solution stayed on their fur. If you are unsure of what to do, contact your veterinarian.

Asked by: Donna
K9 Advantix II should only be used once a month. If you are seeing fleas on your pet these may be new fleas coming from the environment that need to be taken care of. K9 Advantix II will still work on the new fleas for 1 month after being applied; however, you may want to look into flea control for the surrounding environment.

After the 48 hours have passed, can I use a medicated shampoo that kills fleas on my dog? Or should I use regular shampoo?

Asked by: Shoelover23
You may use a flea shampoo after 48 hours, but it will be best to use a natural shampoo. We carry Be Flea Free Shampoo and Natural Chemistry Natural Flea & Tick Shampoo with Oatmeal. These products do not strip the flea and tick topical.

MY dog gets a seizure when I put any kind of heart worm meds on her. This makes her unprotected from mosquitoes. Is there any reports of seizures with this medicine? Are there any of the same ingredients in any heart worm med. that is in this.? 

Asked by: nancy
The ingredients in K9 Advantix are different from those in heartworm medications. However, since your dog has a history of seizures, I recommend consulting with your veterinarian to determine which flea and tick preventative would be the safest for your dog. Your veterinarian knows your dogs medical history and would be able to make the best treatment decisions regarding your pet.

I have a Advantix blue that was for my lab who I now am treating with Bravecto. I would like to treat my 16# dog and my8#dog. How much do I use?  This stuff is so expensive and I have five dogs and two cats so I don't want to waste it

Asked by: Jnmt59
Advantix Blue is for dogs 55 lbs and over. It is not recommended to split the dose to give to a smaller dog. You may end up over- or under-medicating your dog resulting in overdose/toxicities or decreased effectiveness, respectively.

I purchased K9 Advantix II about 3 weeks ago and put a full dose on each of my dogs. Two weeks later, they still had fleas. I took another pouch of K9 and put a little on each dog. they both still have fleas. please help! 

Asked by: mms09
In order for K9 Advantix to kill fleas, they need to bite your pet to ingest the medication. Therefore, any new fleas that attach to your dog may bite him before they ingest the medication and die. This may be causing the itchiness and scratching your dog is experiencing. It is also important to treat the surrounding environment for fleas, to prevent new fleas from attaching to your dog.

How long does skin irritation usually last after application?  My 8-9 lb Shih Tzy / Yorkie mix has been trying to scrach/chew the area of application for 4 days after applying the drops.

Asked by: Dave
Individual sensitivities, while rare, may occur after using any pesticide product for pets. A small percentage of dogs have had adverse reactions to K9 Advantix II. A sensation of burning, tingling, itching, redness or numbness of the skin may occur after topical application. This sensation usually begins 1-2 hours after application. In addition, reactions have occurred in cats that have been exposed to a medicated dog. That is why it is important to separate your cat from a medicated dog for 24 hours. Bayer, the manufacturer of K9 Advantix II, indicates that some of these symptoms will dissipate within 48 hours; however, if your pet is experiencing adverse reactions, please complete the following steps: -Stop applying the medication -Wash your dog with a detergent based soap (Dawn or Palmolive dish detergents work best). Do not scrub the affected area, as this may cause more skin irritation. Please note: This process is applicable for both dogs and cats. -Call your veterinarian -Call Bayer Emergency Support Line at 1-800-422-9874. Let Bayer know your dog is having an adverse reaction to K9 Advantix by calling 1-800-422-9874. This line is staffed 24 hours a day, 7 days a week.

One day after application my Dachshund's fur still has what looks like wet fur where I put the K9 Advantix II. Help!

Asked by: KarenLeah
K9 Advantix should be applied on your pets skin, and not their fur. If you apply the contents on the fur, it may not get absorbed into the skin. You may need to redose your pet if it looks like the solution stayed on their fur. If you are unsure of what to do, contact your veterinarian.

Dog weight is 170 lbs what weight should I buy, is 55lbs and up oka?

Asked by: sg111
Per the K9 Advantix representative, this product is dosed based on body surface area and not by weight. According to the representative, one applicator should be enough for your 170 lb dog. However, they said you can redose more often than once a month as needed. If you are still unsure, please call the 1-800 number located on the K9 Advantix box.

I used Bravecto and my dog is still scratching and digging. When can I put K9 advantage II on him ??

Asked by: Mary
You should wait 12 weeks before applying another flea and tick preventative medication. If your dog is still scratching, he may be coming into contact with new fleas from the surrounding environment. It is important to treat both inside and outside of your home for fleas as well.

My dogs still have fleas on them two weeks after applying the medicine. Can I give them another dose before 30 days

Asked by: Donna
K9 Advantix II should only be used once a month. If you are seeing fleas on your pet these may be new fleas coming from the environment that need to be taken care of. K9 Advantix II will still work on the new fleas for 1 month after being applied; however, you may want to look into flea control for the surrounding environment.
